Abstract
A construction machine typically comprises a mobile chassis having an arm vertically swingably mounted thereon, and a working accessory is detachably retained by the tip end of the arm. The arm has a link arrangement with pin holes at upper and lower portions thereof, and retaining grooves at upper ends thereof. The accessory has pin holes at front and rear portions thereof. Retaining elements such as rings or pin are fixed to the accessory. The retaining rings or pin are fitted in the retaining grooves to position the accessory so connecting pins can be inserted into the pin holes to connect the accessory to the arm.
